Comparative Selection of Demolition Methods Used for Enclosure Structure of A Car Dumper Shed in Rizhao Port
Based on the construction sequence,the enclosure structure of a car dumper shed at Shijiu harbor of Rizhao port is divided into circular&corridor diaphragm concrete walls,curtain grouting anti-seepage structure of foundation pit,foundation treatment of main structure of car dumper shed,foundation treatment of main structure of corridor and foundation pit support system.During the construction of main structure of car dumper shed,it is necessary to dismantle part of enclosure structure,including a part of diaphragm concrete wall and support.Two demolition processes of rope-saw-cutting and blast are compared and analyzed.By studying the technology of demolishing the support of deep foundation pit,thorough understanding of the support form in deep foundation pit is achieved,which will serve as a reference for similar projects,improve the construction quality and efficiency.
